Sintering is a widely used method to agglomerate iron-containing fine-grained materials. In sintering the ore fines, concentrates, fluxes, and coke breeze are thoroughly weighed, moistened, and mixed. The sinter mix is fed on the grate of the sintering machine to make a 0.3–1 m high bed. The grate is an endless strand of slowly moving pallets.
The sinter product mix comprises the products of YuGOK, such as non-fluxed sinter 62% Fe and fluxed sinter 50-57% Fe. The sinter is non-toxic, non-flammable and non-explosive. The sinter is shipped as a bulk commodity by rail using the open-top rolling stock. Production. Fe in the ore is present in the form of oxides or salts combined with gangue.

There have been studies about the low-temperature reduction degradation characteristics of pellets, sinter, and lump ore, [] as well as the softening, shrinking, and melting reduction behavior of all charge materials or just part of them. [3-9]Even though some research has considered all iron-bearing materials (sinter, iron ore pellets, and lump ore), the authors were not able to find ...
sinter raw mix. Coarse and very fine materials were used. The sinter product and the respective productivity rates were compared. It was even possible to produce a good-quality sinter using pellet feed, but at decreasing productivity rate. The results depend to a major extent on the raw materials used and the selection and combination of ...
The sinter mix consisted of micro-pellets, fluxes, coke breeze, and return sinter. For each test, all raw materials including moisture were mixed in drum mixer and the mixed charge was transferred into a pot grate (tube) up to a height of 500 mm bed. 1 mm grate spacing was maintained in the pot to retain finer particles without hearth layer.
rate and return fines rate were adjusted to reach a balanced return fines ratio and the target FeO-content of the sinter. Table 4.The sinter mix in percentage per ore and the chemical composition of the sinter feed ore mixture KBF (10% of SM) Carajas SF (35% of SM) Fabrica SF (25% of SM) Itabira SF (15% of SM) Yandi Fines (10% of SM)
The homogenous blend of iron oxide fines and fine carbon particles have driven a 20%-plus reduction in coke rates. The briquettes' carbon content has reduced the need for imported carbon from Australia for both the mill and its customer's mill, while improving the performance of sinter strands (stiff extrusion removes the fine materials ...

The sinter raw materials (like coarse as well as fine iron ores, ultra-fine ores/pellet feed, additives, dusts, solid fuels, return fines, recycled materials from the steel plant and others) are continuously fed into a high-speed intensive mixer where macro- and micro-mixing of the sinter raw mix takes place.
The invention provides a kind of manufacture method of thin iron ore pellets agglomerate.The raw material of this pellet agglomerate comprises fine iron concentrate powder, rich ore powder, cold and hot return fines material, unslaked lime, Wingdale, additive, coal dust.Made raw pellet ore carries out sintering after rolling one deck coal dust outward.In the proportioning of powdered iron ore ...
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.
The raw sinter mix consists of iron ore, limestone, coke, sinter return fines and binder. ... pellet feed and even the highly abrasive return fines, which are produced during crushing and screening of the finished iron sinter. Moreover, the use of intensive mixers enables considerable savings in the amount of binder and solid fuel consumed ...
lump (>6.3mm) or sinter fines (<6.3mm). The difference for the consumer is that lump can be fed directly into the blast furnace while fines must first go through a process known as sintering where they are agglomerated into crude pellets called 'sinter'. This step is necessary to …
The evolution of the sinter ores, which become finer, on the market and the presence of more and more concentrate and pellet feed constrain steel makers to increase the ratio of ultra-fines material in their sintering process in order to remain competitive regarding the cost of hot metal production.

Lime addition to sintering is a well - established process worldwide. Lime improves sinter mix granulation, permeability and reduces the effect of moisture re-condensation. This ...
Hatch compared the merits of using both pellets and sinter as the main constituents of the blast furnace burden, focusing on blast furnace productivity, environmental performance, solid waste management, and the steel plant energy balance. For this exercise, only sinter fines and fired pellets available in the seaborne market were considered.
produced sinter by various means. Keeping quality has in most cases meant that fine ores as concentrate or even pellet feed has been added to the sinter mix. The increased usage of these types of ores have resulted in larger focus on agglomeration, either by the use of intensive mixers, but also usage of various binders [2].
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
